Abstract
Electrodynamics of the earth’s upper atmosphere has been one of the most important fields of interest in the development of space research. Its situation in the body of outer geophysics is quite original because of its first-order importance in coupling mechanisms, making a local understanding of electric currents and fields almost impossible: coupling between neutral atmosphere and ionospheric plasma motions by dynamo action of the neutral winds; coupling between ionospheric and magnetospheric plasma along the same magnetic field line by means of strong field-aligned conductivities, participating in particular to the equilibrium of the F layer; coupling between magnetospheric and solar-wind plasma motions by generation of the so-called convection electric fields at the magnetopause. Because of the long range of electromagnetic interactions, the global atmospheric circuit cannot be closed until all the region of space enclosed between the lower boundary of the ionosphere and the solar wind/ magnetosphere bow shock is considered.
